Excerpt from Journal of the American Chemical Society, 1881, Vol. 3 At that time, and even now, the generation of ammonium nitrite by evaporation of water was, and is taught, as an established fact. If this were indeed the case, the ozonising chambers present the most favorable conditions for its generation, and the nitrite thus formed would give the same reaction as hydrogen peroxide or ozone, when we came to titrate the water in the ozonisers with an acidified solu tion of potassium iodide. The elaborate experiments of Bohlig, Zabelin and Carius, however, have Shown that this is not true, and that the alleged formation of ammonium nitrite by evaporation of water in air, never takes place when adequate precautions are taken to exclude from the evaporated water, the ammoniacal compounds pre-existent in the atmosphere. Fortunately, therefore, this source of error was not inherent in the experiments themselves, and it only remained to guard against it by very complete washing of the air drawn through the ozonator.
